Application filed August 5,1911. {serial lilo." 642L455.

To all whom it may concern Be it known that I, HENRY P. Remains, of Boston, in the county of Suflollr and State er Massachusetts, have invented cen tain new and useful Improvements in Bea ing and Mixing Devices, of which the following is a specification.

This invention relates toan improved beatingand mixing device.

1o The object of the-invention is to provide a device which shall quickly and mostetfectively'beat up and mix eggs, beverages, and the like, so as to produce a smooth, well blended mixture, in which the ingredients.

are all finely divided and thoroughly mixed, and the whole'mass lightened and aerated.

With the above object in view, the invention consists in a whirling dasher and cutter, which' is forced up and down through the liquid or other matter which is being treated.

The invention will be clearly understood .li'rom an inspection of the accompanying drawing, in wh1chra ininous dasher 10, having apcrtures'lQ, and provided with a plurality ot blades 14-,-

which extend. upwardly tl'ieret'ron'r at its periphery and are bent inwardly toward the center. The dasher and blades may be.{madc of sheet metal, and are preferably made integral. i

The blades are located with their broad sides or faces in their plane of rotation, so that their narrow edges act as rotary cutters to cut up the substances or ingredients contained in the receptacle, while their broad faces act to beat and thoroughly mix the contents of the receptacle by their reciprocatory motion. These blades may be so located and shaped that they come into comparatively close proximity with the Walls of the receptacle, as shown in Fig. l, and'when operated, the dasher with its blades constitutes a whirling dasher and cutter.

The dasher 10 is secured to the lower end of a spiral stem 16,;which is substantially rectangular in cross-section, and is adapted to pass freely through a guiding aperture 18, formed in a bridge plate or guide 20, which is secured to the under side of a cover '22. The upper end of the stem 16 is provided with an operating knob 24, which is rotatably mountedthereon/ The cover 22 is formed with a flange or lip 23 at 'lts lower edge, which is adapted to fit the exterior of the upper edge of the receptacle 26 in. which the substances to be beaten and mixed are contained. This cover is provided at its center with an aperture 27 through which the stem 16 passes. it desired a pouring opening may be provided in the cover above'the flange 23, and this opening may be divided into a series of slits 29 by bars 80.

The operation of the device is as follows: The knob 24 is grasped by the operator and reciprocated up and down rapidly. The

spiral stem 16 in reciprocating through the rectangular guiding aperture 18 is caused to rotate back and forth, and with it the dasher 10 andthe blades 14. The blades by their actio": operate to cut up and finely divide thematerial contained in the re iceptacle 26, and the apertures 12 allow the material to pass back and forth through the dashcr, whereby the mass is thoroughly cutup, mixed and aerated, and rendered uniform and smooth intexture.

It will be understood that the receptacle 26 may be of any desired form and size, according to the requirements and uses for which it is intended, and it will also be understood that the pouring opening may be omitted from the cover if desired.

While I have illustratedand described a preferred embodiment of the invention, I am aware that many modifications can be made therein by' any person skilled in the art without departing from the scope of the invention as expressed in the claim. Therefore i: do not wish to be liinitedto all the 1gletails of construction shown and described,
